T all whom it may concern:

' Be it known that we, ELLswoR'rH S. BRY- ANT, ALEXANDER WILLIAM FrNLAYsoN, and GEORGE R. OoULs, of Detroit, in the county of Vayne and State of Michigan, have invented new and useful Improvements in Gas- Making Apparatus; and .we do hereby declare that the following is a full, clear, and exact description thereof, reference being had to the i@ accompanying drawings7 which form a part of this specification.

'This invention relates to certain new and useful improvements in devices for manufacturing illuminating-gas, adapted to be used in each household for the manufacture of such gas for home consumption. l

The invention is designed to furnish ready and economical means for the manufacture of gas by destructive distillation, bythe use of 2O which the evils arising from condensation in the pipe-service are reduced to the minimum.

The invention consists in the peculiar construction of the parts and their various comtegralpr in separate parts properly secured together by gas-tight joints, as shown at H.

l. is the retort, made in the usual way, closed at one end, while the front is provided with 55 an outwardlyfprojecting flange, c, having ears d cast integral thereon, by means of which the cover K is hinged to the front of such re tort. This iiange c has also formed upon it loop-flanges e, which hold the bar L in posi- 6o any desired shape, although shown in the 7o drawings to be cylindrical or round to t within the combustion-ehamber of an ordinary cooking-stove, N, and be inserted there in, if desired, through the fuel-door in one To remove the 6 5 binations and operations, as more fully hereinafter described.

Figure l is a sectional elevation showing our invention as iu operation. Fig. 2 is a perspective section showing one end of our improved retort. Fig. 3 is a sectional plan showing the retort in place in the tire-box or end thereof. Apipe, O, conducts the gas from the retort into the lower part ofthe water-chain berA, whereby the gas, in passing up through the water, is washed and discharged into the chamber G, where it passes through the purifying mass upon the shelves and thence to 8o the gas-holder, whence it is taken out by the 5 5 the purpose of washing the gas,

combustion-chamber of a cooking-stove or range.

In the accompanying drawings, A represents a suitable vessel for holding water for This vessel is surmounted by a dome, B, whichinay be cast integral with the vessel, or secured thereto in any of the known ways of making pipejoints. One or more perforations, a, in this 4o dome B allow the escape of the gas into the chamber C, which is fitted with a series of eross-supports,.D, which are designed to contain or hold slaked lime or otherof the known purifying materials for gas; and this chamber 45 is surmounted also by a dome or cap, E, in

the top of which there are one or more apertures, b, to allow the gas to escape into the gas-holder F, which rises and falls in the water seal G. The vessel A, with its cap or dome 5o B, the chamber G, with its cap or dome E, and

the walls of the water seal G may be cast inusual servicepipes to the burners.

P is a branch pipe, connecting with the pipe O at any convenient point, so that the open end of said pipe I? may belet into the stove pipeor flue Q, and at the point of intersection of this branch pipe P with the pipe O a two-way valve is inserted, so that if more gas is made than it is desired to discharge into the holder F the iiow into such holder may be cut 9o off by turning the two-way cock and allowing the extra or surpertluous gas to be discharged into such flue.

It will readily be seen that the retort being lled with wood or coal, the ordinary fire of the cook-stove required for culinary and other purposes of the household will furnish the requisite heat for the destructive distillation of the contents of the retort. All the objections to making gas for household consump` roo tion in this way are removedby the apparatus attached thereto for washing and purifying the gas. The same result might be obtained by the use of a kettle suitably connected with the gas-ho1der and its attachments, such kettle occupying one of the boiler-holes above the fire-chamber and illed with the material from which the gas is to be destructively distilled and the cover suitably luted upon the top of such kettle.

Pipes h andz' afford means for filling and discharging the chamber A, when necessary.

We are aware that it is not new-to pass the gas generated in a retort through a washingchamber and thence through a purifyingchamber, and therefore do not claim such, broadly.

Our invention lies in the peculiar construction, arrangement, and adaptation of parts, as specified in the appended claims.

That we claim as our invention is-M 1. The combination, with a retort, of a gaswashing chamber connected therewith, a purifyingchamber formed integral with said washing-chamber and provided with a dome having a Water seal, and a gas-holder above said dome working in said water seal, substantially as described.

2. The combination, with a retort, of a gas washing chamber connected therewith and provided with a dome, a purifying-chamber arranged above the washing-chamber and having communication therewith through perforations in said dome, a dome to the purifying-chamber having perforations, and a gasholder above said dome, substantially as described.

3. The combination, with a retort, of a gaswashing chamber connected therewith and provided with a perforated dome, a purifying-chamber arranged above thewashingchamber and provided with racks D and a perforated dome, a water seal on said dome, and a gas-holder working in said water seal, as set forth.

4t. The chambers A D, formed integral and separated by a perforated dome, combined with the detachable perforated dome E, having formed integral therewith the water seal G, substantially as and for the purposes specified.
